Abstract
The utility model relates to a photon-generated degradable film special for sugarcane, which is characterized in that the film consists of a middle photo-degradation part and biodegradation parts on both sides of the photo-degradation part; the photo-degradation part is 30-50 cm wide; the biodegradation parts are located on both sides of the photo-degradation part and are 5cm wide; the film is 0;004-0;008 mm thick and 40-60 cm wide; photo-degradation occurs on the middle photo-degradation part under illumination; and the biodegradation parts covered by soil on both sides initialize biodegradation. The problems that the photon-generated degradable film buried is hard to degrade and a starch degradable film is high in cost are solved. The photon-generated degradable film special for sugarcane is designed according to the growth regular of sugarcane, the degradation induction time is 90-150 days, the degradation is thorough, the labor investment of a film uncovering link is reduced, ad the sugarcane planting cost is reduced.
Description
Technical field
The present invention relates to the degradation plastic mulch goods, the special-purpose photoproduction degradative plastic film of especially a kind of sugarcane.
Background technology
Mulch film is since applying the seventies, and tangible water conservation and moisture-holding has been played in the application on most of cereal crops, economic crops, improves the effect of soil temperature, and economic benefit is obvious, and popularizing area constantly enlarges.Because the life-span of conventional mulch film in soil reaches 150 years; Be difficult to degraded, after long-term the use, constantly increase in the residual quantity of soil; Soil physico-chemical property has been caused serious destruction; Hindered the extension of root system of plant, and hindered plant, caused the underproduction significantly of crops deep soil nutrient and absorption of water.
For eliminating the pollution of common ground film to environment, the development and use of degradative plastic film become the research focus of countries such as the U.S., Japan, European Union, and present degradative plastic film mainly contains Biodegradable mulch, photodegradation film, the two degradative plastic films of photoproduction.The problem that exists mainly contain cost height, degraded not thoroughly, degradation time is difficult to control etc.Controlled degradation time, degraded are thoroughly, the environment-friendly type degradative plastic film will be the R&D direction of degradative plastic film cheaply.
Sugarcane is the southern important economic crops of China, and wherein the upland sugarcane area accounts for more than 80%, and plastic mulching is adopted in the plantation of sugarcane winter-spring season, has significantly improved emergence rate, and tangible Yield-increasing and sugar-increasing effect is played in raising the output to upland sugarcane.But after covering conventional plastic mulching, take off the expense that film also needs 1.5 manual works, increased the cane planting cost, caused the residual of mulch film simultaneously.For solving the problem of the long-term lack of water in cane planting zone, China south, press for the new technology new product of development drought resisting, environmental protection and abridged edition.And degradative plastic film has played the saving cost when playing drought-resistant water-preserving, saves the function of labour and protection environment.
At present the subject matter that exists of photodegradation film have the degraded induction time short, be embedded under ground portion and be difficult to degraded; And the special-purpose degradative plastic film of sugarcane needs long degraded induction period, could satisfy the demand of sugarcane normal growth.
Summary of the invention
The utility model proposes the special-purpose photoproduction degradative plastic film of a kind of sugarcane, can solve the problem that is difficult to degrade after photodegradation film buries, and can prolong the induction period of degrading, and satisfies the requirement of sugarcane production.The utility model is realized through following technical scheme:
The special-purpose photoproduction degradative plastic film of a kind of sugarcane, it is characterized in that mulch film by the light degradation part of centre and the biological degradation part of light degradation part both sides totally three bands constitute.
Described light degradation part mainly forms width 30-50cm by polyethylene and light degradation cooperation.
Described biological degradation part is a base-material with starch, and the width of each side respectively is 5cm.
Described ground film thickness is 0.004-0.008mm, and width is 40-60cm, and light transmittance is more than 90%.
The special-purpose photoproduction degradative membrane of this sugarcane that the utility model proposes, the light degradation part in the middle of characteristics are can all be exposed under the illumination, and light degradation takes place; Both sides are Biodegradable films, are covered the back by biological degradation by soil; Solved the problem that is difficult to degrade after photodegradation film buries, mulch film starch usage amount only accounts for 16-25%, has overcome the starch mulch film and has made the high problem of degradative plastic film cost.The photoproduction degradative plastic film is according to the growth rhythm design of sugarcane, and effectively the control degradation time had drought resisting, water conservation, heat preservation effect at 90-150 days; Can satisfy the demand of sugarcane normal growth, it is comparatively thorough to degrade, and has reduced labour's input that cane planting is taken off the zona joint, reduces the cane planting cost.

Embodiment
With the hard ester acid of sensitising agent iron, dibutyl dithiocaarbamate iron, hard ester acid cerium, hard ester acid rare earth
,Polyvinyl resin is according to the mass fraction ratio of 1:2:1:1:5, and adds micro-coupling agent, processing aid, abundant dispersing and mixing in high-speed mixer, and mixing gross mass each time is 50kg, mixes the back and adopts double screw extruder that mixture is caused the light degradation master batch.Selecting low density polyethylene, LLDPE LLDPE is the major ingredient of degradative plastic film; With the abundant mixing of light degradation masterbatch; Fully mix back polyethylene addition and be 90%, the ratio of degradable master batch is 10%; Process the compound material of light degradation, final ferric stearate 0.05%, dibutyl dithiocaarbamate iron 0.05%, hard ester acid cerium 0.1%, hard ester acid rare earth 0.1%; Corn starch is added antioxidant 1010 process the starch-base biodegradation material.Adopting the double-colored function mulch film of black and white unit that the compound material of light degradation, biological degradation material are processed thickness is 0.004-0.008mm, and width is the mulch film photoproduction degradative plastic film of 40-60cm, and the mulch film rolling is packaged as the finished product mulch film, under the lucifuge condition, preserves.
Being chosen in winter-spring season grows cane; Put into fertilizer, agricultural chemicals, sugarcane kind stem at the plantation ditch, with plastic mulching machine or manpower the biological degradation of photoproduction degradative plastic film is partly covered with soil behind the earthing, light degradation partly is exposed to ground; Cover into the pan tile shape, once cover and to take off film.
